Description

Technical Field

[0001] This invention relates to the field of electroplating wastewater treatment technology, specifically to a waste liquid collection device for electroplating processes. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics.

[0003] Chinese patent CN216837457U, authorized and published on June 28, 2022, discloses a waste liquid collection device for electroplating treatment, which includes a tank, a tank cover, a feeding bin, an inlet pipe, an outlet pipe, an inner tank, a transfer pipe, a solenoid valve, a stirring assembly, and a separation assembly. The separation assembly includes a propeller, a conveying pipe, and a conveying component. The conveying pipe is fixedly connected to the tank and detachably connected to the transfer pipe. The conveying pipe has a filter hole located on the side of the conveying pipe away from the transfer pipe. The propeller is rotatably connected to the conveying pipe.

[0004] In the aforementioned application, solid impurities and electroplating waste liquid are separated through the filter holes of the conveying pipeline, and the generated solid impurities are then discharged by a propeller. However, when the electroplating wastewater reacts with the precipitant to generate large-volume solid impurities, the solid impurities may clog the transfer pipe, thus affecting the use of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a waste liquid collection device for electroplating processes, solving the problems mentioned in the background section. To achieve the above objectives, this invention provides the following technical solution: a waste liquid collection device for electroplating processes, comprising: The waste liquid collection chamber and the treatment chamber are equipped with a waste liquid input pipe and a precipitant input pipe at the top of the treatment chamber, a stirring plate driven by a servo motor is installed inside the treatment chamber, and a transfer pipe is installed at the bottom of the treatment chamber. The bottom of the stirring plate is equipped with a bevel gear, the interior of the processing chamber is equipped with a sliding plate via an elastic telescopic rod, the side of the sliding plate is equipped with a unclogging block, a transmission component for transmission is assembled between the bevel gear and the unclogging block, the side of the transfer tube is equipped with a striking component, and the interior of the processing chamber is equipped with an auxiliary stirring component.

A bevel gear two and a sprocket one are fixedly connected to the outer side of the rotating rod one, with the bevel gear two meshing with the bevel gear one. A chain one is mounted on the outer side of the sprocket one, and a sprocket two and a cam are fixedly connected to the outer side of the rotating rod two. This device design allows the unblocking block to reciprocate at the inlet of the transfer pipe, breaking down larger solid impurities, reducing the likelihood of solid impurities clogging the transfer pipe, and making the device easier to use.

[0007] Preferably, the end of the chain away from the sprocket is fitted to the outer side of the sprocket.

[0009] Preferably, the striking assembly includes a transmission rod mounted on the bottom of a bevel gear, a rotating disk fixedly connected to the bottom of the transmission rod, a fixing block fixedly connected to the bottom of the rotating disk, a connecting rod rotatably connected to the outer side of the fixing block, a limiting rod slidably connected to the bottom of the processing chamber, and a striking rod fixedly connected to the bottom of the limiting rod. By configuring the striking assembly, the striking rod can move horizontally towards the transfer tube and strike it. The struck transfer tube will vibrate to a certain extent, further reducing the possibility of the transfer tube being blocked by solid impurities.

[0010] Preferably, the striking rod is located on the side of the first connecting rod and is hinged to the first connecting rod.

[0011] Preferably, the auxiliary agitation assembly includes a sprocket three fixed to the outside of a rotating rod, a chain two mounted on the outside of the sprocket three, a drive rod rotatably connected to the side of the treatment chamber, a sprocket four and an arc-shaped agitator plate fixedly connected to the outside of the drive rod, and a passage groove formed on the side of the arc-shaped agitator plate. By setting up the auxiliary agitation assembly, the waste liquid and precipitant near the transfer pipe in the treatment chamber can be fully agitated, further improving the reaction efficiency of the device.

[0012] Preferably, the end of the second chain away from the third sprocket is fitted to the outer side of the fourth sprocket.

[0013] Preferably, five arc-shaped stirring plates are provided, and the five arc-shaped stirring plates are arranged in a circumferential array about the drive rod.

[0014] Preferably, the cross-sectional shape of the channel is adapted to the cross-sectional shape of the unblocking block.

[0015] This invention provides a waste liquid collection device for electroplating processes. It has the following beneficial effects: (1) When the waste liquid collection device for electroplating is stirred and chemically reacted with the waste liquid and precipitant in the process, the stirring plate in the rotating state can drive the first bevel gear to rotate. In conjunction with the first rotating rod, the second bevel gear, the first sprocket, the first chain, the second rotating rod, the second sprocket, the cam, the elastic telescopic rod and the sliding plate, the unblocking block can move back and forth at the inlet of the transfer pipe to break up the large solid impurities, reduce the possibility of solid impurities clogging the transfer pipe, and make the device easier to use.

[0016] (2) When the bevel gear is rotating, the waste liquid collection device of the electroplating process can drive the transmission rod assembled at the bottom of the bevel gear to rotate. With the help of the rotating disk, the fixed block, the connecting rod and the limiting rod, the striking rod can move towards the transfer tube in the horizontal direction and strike the transfer tube. The transfer tube that is struck can generate a certain degree of vibration, which further reduces the possibility of the transfer tube being blocked by solid impurities.

[0017] (3) When the rotating rod 1 rotates, it can drive the sprocket 3 that is fixedly connected to it to rotate. In conjunction with the chain 2, drive rod, sprocket 4, arc-shaped stirring plate and through tank, the waste liquid and precipitant near the transfer pipe in the treatment chamber can be fully stirred, which further improves the reaction effect of the device.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1, please refer to Figures 1-5 A waste liquid collection device for electroplating treatment, comprising: The system includes a waste liquid collection chamber 100 and a treatment chamber 200. The top of the treatment chamber 200 is equipped with a waste liquid inlet pipe 300 and a precipitant inlet pipe 400, respectively. Inside the treatment chamber 200 is a stirring plate 500 driven by a servo motor, and at the bottom is a transfer pipe 600. Waste liquid and precipitant are fed into the treatment chamber 200 through the waste liquid inlet pipe 300 and the precipitant inlet pipe 400, respectively. The servo motor is activated, causing the stirring plate 500 to rotate, stirring and chemically reacting the waste liquid and precipitant within the treatment chamber 200. Subsequently, the transfer pipe 600 is opened, allowing the treated waste liquid and solid impurities to be discharged through the transfer pipe 600. A bevel gear 701 is mounted on the bottom of the stirring plate 500. When the treated waste liquid and solid impurities are discharged through the transfer pipe 600, the rotating stirring plate 500 drives the bevel gear 701 mounted on its bottom to rotate.

[0027] Inside the processing chamber 200, a sliding plate 710 is mounted via an elastic telescopic rod 709. A unblocking block 711 is mounted on the side of the sliding plate 710. A transmission component for transmission is mounted between the bevel gear 701 and the unblocking block 711. The transmission component includes a rotating rod 702 and a rotating rod 706 rotatably connected to the side of the processing chamber 200, respectively. A bevel gear 703 and a sprocket 704 are fixedly connected to the outer side of the rotating rod 702. When the bevel gear 701 rotates, it drives the meshing bevel gear 703 to rotate, and the rotating bevel gear 703 drives the fixedly connected rotating rod 702 to rotate.

[0028] Bevel gear 703 meshes with bevel gear 701. Chain 705 is mounted on the outer side of sprocket 704. Sprocket 707 and cam 708 are fixedly connected to the outer side of rotating rod 706. The end of chain 705 away from sprocket 704 is mounted on the outer side of sprocket 707. When rotating rod 702 rotates, it drives sprocket 704, which is fixedly connected to it, to rotate. This, in conjunction with chain 705 mounted on the outer side of sprocket 704, causes sprocket 707, which is driven by chain 705 and sprocket 704, to rotate.

[0029] The cam 708 is located at the top of the unblocking block 711 and is in contact with it. When the cam 708 rotates, it drives the unblocking block 711 to move back and forth at the inlet of the transfer pipe 600, breaking up larger solid impurities and reducing the possibility of solid impurities clogging the transfer pipe 600, making the device easier to use.

[0030] In use, waste liquid and precipitant are fed into the treatment chamber 200 through waste liquid inlet pipe 300 and precipitant inlet pipe 400, respectively. The servo motor is activated, driving the stirring plate 500 to rotate, stirring and chemically reacting the waste liquid and precipitant in the treatment chamber 200. Subsequently, the transfer pipe 600 is opened to discharge the treated waste liquid and solid impurities. At this time, the rotating stirring plate 500 drives the bevel gear 701 mounted at its bottom to rotate, causing the bevel gear 701 to drive the meshing bevel gear 703 to rotate. The rotating bevel gear 703 then drives the rotating rod 702 fixedly connected to it to rotate, causing the rotating rod 702 to drive the sprocket 704 fixedly connected to it to rotate. This, combined with the chain 705 mounted on the outside of the sprocket 704, allows the chain to... The sprocket 707, which is connected to the sprocket 704, rotates. The rotating sprocket 707 drives the rotating rod 706, which is fixedly connected to it, to rotate. The rotating rod 706 then drives the cam 708, which is fixedly connected to it, to rotate. When the protruding part of the cam 708 rotates to the unblocking block 711, it can squeeze the unblocking block 711 from the top position. This causes the unblocking block 711 to move the sliding plate 710, which is fixedly connected to it, and to move downward by compressing the elastic telescopic rod 709 through the sliding plate 710. As the protruding part of the cam 708 moves away from the unblocking block 711 with the rotation, the unblocking block 711 loses its restraint and can be reset under the action of the elastic telescopic rod 709. In this way, the unblocking block 711 can move back and forth at the inlet of the transfer pipe 600 to break up larger solid impurities.

[0031] Example 2, please refer to Figures 1-7 Based on Embodiment 1, a striking assembly 800 is mounted on the side of the transfer tube 600. The striking assembly 800 includes a transmission rod 801 mounted on the bottom of the bevel gear 701. When the bevel gear 701 is rotating, it can drive the transmission rod 801 mounted on the bottom of the bevel gear 701 to rotate.

[0032] A rotating disk 802 is fixedly connected to the bottom of the transmission rod 801. When the transmission rod 801 rotates, the rotating disk 802 fixedly connected to it will also rotate.

[0033] A fixed block 803 is fixedly connected to the bottom of the rotating disk 802, and a connecting rod 804 is rotatably connected to the outside of the fixed block 803. When the rotating disk 802 rotates, it can drive the fixed block 803 fixedly connected to it to rotate together, so that the fixed block 803 drives the connecting rod 804 rotatably connected to it to move.

[0034] A limiting rod 805 is slidably connected to the bottom of the processing chamber 200. A striking rod 806 is fixedly connected to the bottom of the limiting rod 805. The striking rod 806 is located on the side of the connecting rod 804 and is hinged to the connecting rod 804. When the connecting rod 804 moves, it can drive the striking rod 806 to move, causing the striking rod 806 to move horizontally toward the transfer tube 600 and strike the transfer tube 600. The transfer tube 600 will vibrate to a certain extent when struck, further reducing the possibility of the transfer tube 600 being blocked by solid impurities.

[0035] In use, based on Embodiment 1, when the bevel gear 701 is rotating, it drives the transmission rod 801 mounted at the bottom of the bevel gear 701 to rotate, causing the transmission rod 801 to drive the rotating disk 802 fixedly connected to it to rotate. The rotating disk 802, in turn, drives the fixed block 803 fixedly connected to it to rotate as well, causing the fixed block 803 to drive the connecting rod 804, which is rotatably connected to it, to move. When the connecting rod 804 moves closer to the transfer tube 600, it drives the striking rod 806 hinged to the connecting rod 804 to move as well. The striking rod 806 is fixedly connected to the limiting rod 805, while the limiting rod 805 is slidably connected to the processing chamber 200. During the movement, the striking rod 806 is restricted by the processing chamber 200, causing the connecting rod 804 to drive the striking rod 806 to move horizontally toward the transfer tube 600 and strike the transfer tube 600. The transfer tube 600, when struck, will vibrate to a certain extent.

[0036] Example 3, please refer to Figures 1-9 Based on Embodiments 1 and 2, the processing chamber 200 is equipped with an auxiliary stirring assembly 900, which includes a sprocket 901 fixed to the outside of the rotating rod 702. When the rotating rod 702 rotates, it drives the sprocket 901 fixedly connected to it to rotate.

[0037] A chain 902 is mounted on the outer side of sprocket three 901. A drive rod 903 is rotatably connected to the side of the processing chamber 200. A sprocket four 904 and an arc-shaped agitator plate 905 are fixedly connected to the outer side of the drive rod 903. When sprocket three 901 rotates, it cooperates with the chain 902 mounted on the outer side of sprocket three 901 to cause sprocket four 904, which is connected to sprocket three 901 through chain 902, to rotate.

[0038] One end of chain two 902, away from sprocket three 901, is mounted on the outer side of sprocket four 904. Five arc-shaped agitator plates 905 are arranged in a circumferential array about drive rod 903. When drive rod 903 rotates, it causes the multiple arc-shaped agitator plates 905 fixedly connected to it to rotate, thus fully agitating the waste liquid and precipitant located there.

[0039] The side of the arc-shaped stirring plate 905 is provided with a through groove 906, and the cross-sectional shape of the through groove 906 is adapted to the cross-sectional shape of the unblocking block 711. Because multiple arc-shaped stirring plates 905 are provided with through grooves 906, the arc-shaped stirring plates 905 are not restricted by the unblocking block 711.

[0040] In use, based on Embodiment 1 and Embodiment 2, when the rotating rod 702 rotates, it drives the sprocket 901 fixedly connected to it to rotate. In conjunction with the chain 902 mounted on the outside of the sprocket 901, the sprocket 904 connected to the sprocket 901 via the chain 902 rotates. The rotating sprocket 904 drives the drive rod 903 fixedly connected to it to rotate, which in turn drives the multiple arc-shaped stirring plates 905 fixedly connected to it to rotate, thus fully stirring the waste liquid and precipitant located there. Moreover, each of the multiple arc-shaped stirring plates 905 has a through groove 906, so that the arc-shaped stirring plates 905 are not restricted by the unblocking block 711.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
